<h2>Hawaian island chain hotspot Potassium-Argon ages</h2>

<h3>Description</h3>

<p>K-Ar Ages (millions of years) and distances (km) from Kilauea 
along the trend of the chain of Hawaian volcanic islands and
other seamounts that are believed to have been created by a
moving &quot;hot spot&quot;. The age of Kilauea is given as 0-0.4 Ma.

<h3>Details</h3>

<p>For details of the way that errors werre calculated, refer to the
original papers. See also the comments under <code>hotspots2006</code>.
In general, errors do not account for geological uncertainty.
